Description

Technical Field

[0001] The utility model relates to the technical field of cup covers, in particular to a cup cover. Background Art

[0002] There are many types of cup lids available today. Straws integrated into the lid are common, and for easier water intake, there are also pop-up straw designs on the market. When the lid is opened, the spring forces the straw to pop out, making it easier to use. For example, the patent application (patent application number: 202311721676.5) is named: Flip-top double drinking cup cover, which includes a large cover, a top rod is installed through the top of the large cover, and the surface of the top rod is fixedly sleeved with an O-ring on the top of the large cover. A fixed rotating shaft is installed through the top of the large cover, and a notch is opened at the bottom of the fixed rotating shaft. The top of the top rod is rotatably connected to the flip cover through the fixed shaft, and the bottom of the top rod is rotatably connected to the connecting rod. A torsion spring is installed between the surface of the connecting rod and the large cover, and a shell is welded to the bottom of the connecting rod. A fixed plate is provided inside the shell, and a limiting card is welded on the back of the fixing plate. A straw is placed inside the limiting card, and a hose is fixedly sleeved on the bottom of the straw. A limiting spring is bolted between the front of the fixing plate and the shell through a spring fixing plate. A fixing rod is welded on the front of the fixing plate, which can realize a dual drinking mode with a single drinking port. You can decide whether to use a straw according to your own needs. However, when the aforementioned operating cup lid is in the pipette water-suction mode, the pipette is secured or unlocked by rotating the rotating plate, thereby locking or unlocking the pipette, thereby enabling the cup lid to be used for drinking directly or through the pipette water-suction mode. In the aforementioned structure, the structure for securing the pipette is relatively complex, the rotating plate is inconvenient to use, and the mounting position of the rotating plate is exposed to the outside, making it susceptible to contamination. Furthermore, the neatness of the cup lid is not satisfactory. Utility Model Content
